Tender mini lime pound cakes with a bright citrus flavor, a light brush of rum, and a buttery lime icing that sets into a sweet-tart finish.
Spring can be a little dramatic. One day the wind is rattling the windows, the next there are birds singing outside before breakfast. Even when the weather still feels cold enough for a sweater, the first green leaves and small flowers are a reminder that brighter days are coming.
That change in the season always makes light, citrusy bakes feel especially welcome. These mini lime pound cakes are exactly that kind of recipe: fresh, tender, buttery, and just sweet enough. They are small enough to serve individually, pretty enough for a gathering, and simple enough to enjoy with coffee or tea at home.
These mini lime pound cakes have the charm of a tea-time dessert, with a soft crumb and a glossy citrus icing that makes them feel special without being fussy.
The cakes are rich in the way a good pound cake should be, but the lime keeps them from tasting heavy. A little rum brushed over the warm cakes adds moisture and depth, while the lime frosting brings a clean, tart finish. Slice them into small pieces for a dessert tray, serve them whole as individual cakes, or decorate them with berries, flowers, or candied citrus for a more elegant presentation.
Fresh lime can be tricky in cake recipes. The flavor is bold before baking, but oven heat softens and mutes citrus. Adding too much juice can also throw off the balance of the batter, making the cakes dense or causing them to sink. This recipe solves that problem by relying mostly on lime zest, which carries concentrated flavor without adding too much liquid.
Fresh lime zest, a tender pound cake crumb, and a buttery citrus glaze make this mini cake recipe a bright choice for spring baking, brunch, afternoon tea, or a simple homemade dessert.
The Perils of Baking Lime Pound Cake
Lime and lemon flavors often fade during baking, especially when they are used only as juice. The temptation is to add more juice, but that can make a pound cake difficult to manage. Too much acidity changes the structure of the batter and may prevent the cake from rising properly. The result can be a cake that is heavy, gummy, or sunken in the center.
The best way to build a clear lime flavor is to use plenty of zest and only a measured amount of juice. Letting the zest sit in lime juice before mixing it into the batter helps soften its texture, so it blends more smoothly into the cake. This step gives the finished mini pound cakes a stronger citrus aroma without compromising the fine, moist crumb.
This recipe also uses both butter and coconut oil. The butter adds classic pound cake flavor, while the coconut oil helps create a soft texture. After baking, the warm cakes are brushed with rum, which is optional but adds extra moisture and a subtle richness. The lime frosting is made with melted butter, powdered sugar, fresh lime juice, and vanilla, creating a smooth icing with a sweet-tart finish.
Another helpful difference is the mixing method. Instead of creaming butter and sugar with a mixer, the batter begins in a food processor. The sugar, lime zest, lime juice, eggs, vanilla, butter, and oil are blended into a smooth emulsion before being combined with the dry ingredients. This creates a tender, fine-textured pound cake without a long mixing process. The batter comes together quickly, which is useful because zesting several limes takes a little patience.

Mini Lime Pound Cakes
8 or 9 mini loaf cakes
45 minutes
25 minutes
1 hour 10 minutes
These mini lime pound cakes are tender, sweet, and full of fresh citrus flavor. A light brush of rum keeps the cakes moist, and the buttery lime frosting adds a bright, tangy finish.
If you prefer one larger cake, the batter can be baked in a standard loaf pan. Grease and flour the pan before adding the batter, then bake at 350 degrees for about 70 to 80 minutes, or until a tester inserted into the center comes out clean.
Ingredients
FOR THE LIME POUND CAKES:
- 3 tablespoons lime zest, from about 9 limes; save a few of the limes for the frosting
- 2 tablespoons lime juice
- 8 tablespoons butter, ½ cup or 1 stick
- 8 tablespoons coconut oil
- 1 ½ cups unbleached all-purpose flour, minus 2 tablespoons
- 2 tablespoons cornstarch
- 1 teaspoon baking powder
- ¾ teaspoon salt
- 1 ¼ cups granulated sugar
- 4 large eggs, at room temperature
- 1 teaspoon pure vanilla extract
- ⅛ to ¼ cup white rum, optional
FOR THE LIME FROSTING:
- ¼ cup butter, 4 tablespoons or ½ stick, melted
- 1 ¾ cups powdered sugar, also called confectioners’ sugar
- 3 tablespoons freshly squeezed lime juice
- ½ teaspoon pure vanilla extract
Instructions
MAKE THE LIME POUND CAKES:
- Preheat the oven to 350 degrees. Line 8 or 9 cavities of a mini loaf pan with paper liners. After lining the pan, lightly spray the liners and pan with nonstick spray so the cakes release more easily. You can also grease and flour the cavities instead of using liners.
- Place the lime zest in a small bowl with the lime juice. Let it sit for 10 minutes to soften the zest and help release the citrus oils.
- Add the butter and coconut oil to a large measuring cup. Melt in the microwave for about 45 seconds to 1 minute on high heat, then whisk until combined.
- In a medium bowl, whisk together the flour, cornstarch, baking powder, and salt.
- Add the sugar to the bowl of a food processor fitted with the chopping blade. Add the softened lime zest and juice, eggs, and vanilla. Process for about 5 seconds, just until combined. With the food processor running, pour in the melted butter and coconut oil through the feed tube in a thin, steady stream. This should take about 20 to 30 seconds.
- Pour the wet mixture into the flour mixture and stir just until combined. Divide the batter evenly among the prepared mini loaf cavities, filling each about ¾ full. If your pan has extra empty cavities, fill those halfway with water before baking to help protect the pan.
- Bake for about 25 minutes, or until a toothpick inserted into the center of a mini loaf comes out without raw batter.
- Place the pan on a wire rack and let the cakes cool for 5 minutes. Carefully remove the warm cakes from the pan and transfer them to another wire rack. Brush the tops with rum, if using. Let the cakes cool completely before frosting.
MAKE THE LIME FROSTING:
- Add the melted butter, powdered sugar, lime juice, and vanilla to a medium bowl. Stir until smooth and no lumps of powdered sugar remain. Spread a generous amount of frosting over each cooled cake. Let the cakes rest for about 10 minutes so the frosting can set before serving. Store leftovers in an airtight container at room temperature for up to 2 days.
Notes
- Decorate the mini lime pound cakes with flowers, fresh berries, or candied citrus slices for a pretty finish.
